Went to see a short imax film about the canyon and its history ,, typically American in style ,, in so much as it was great ,, felt like you were in a helicopter going through the canyon and on a boat on the rapids , it was so good Sharon felt airsick without leaving her seat ( softy ).Only a very short drive to the entrance of the park the next morning and to the visitors centre which was our first view from the south rim ,, it was truly amazing and i dont think i can do it justice in trying to describe it . It just has to be seen to be believed . Spent the morning walking the 3 miles or so along the rim , thought this was the best option as opposed to the mule trekking or white water rafting at our age !! The other 8 mile we jumped on the shuttle system covering the inaccessable bit ,,, it really was a wonderful day .Drove to Kingsman for the night before heading for Vegas via the Hoover Dam ,, brill bit of engineering you just wonder why they thought of putting it where they did , must have been on danger money when they built it ,, or a bit stupid ! Not content with having done that they are now trying to build a superb bridge across the canyon next to it ,, mad , but looks hellishly impressive .
